Continuation of Thread: Drag race - Kirkham 65 side-oiler vs Ferrari 458 Italia

[Excaliber]

For most of us it was never a question of power in Dan's car, it was a question of traction!

We couldn't even figure out what tires he was running for sure! The video reveals he hooked up real good, MUCH better than I expected. AND a higher rpm launch than I expected. Track prep with the sticky stuff proved to be a deciding factor, without a doubt.

I doubt one post "crossbreeder" had a clue about what tires Dan was running, if so, it means his post is BS and he knows nothing about drag racing OR Cobras!

I was glad to see Dan pull it off. Tom should have turned off the traction control and auto shifter when he seen Dans car hook like that. He could have made it alittle closer.

unstuck the sticky...

It was a great ride while it lasted.

I'm hoping they go with the road race next.

Because he LOST. No shame in losing to a beast like the Kirkham but his ego may be a bit bruised

I hope Tommy posts at some point, it would be great to hear his take on the events on race day.

Yes he did lose the bet, but he gave it his best shot and it was Dan's talent and car that won the day.

I would say both Dan and Tommy have the respect of a lot of the Cobra guys here.

Very well said.

Please post a link to the final result. I can't go back 11 pages hoping to find it...
I take it the Cobra has won?

I get a kick out of all of these guys talkinmg about dynos being juiced and all of this stuff. I know my dyno my correct because my NHRA Stock and Super Stock drag race customers run what my dyno says they will. Just dyno tested a 69 428CJ Super Stock engine that has to have stock compression with stock carburetor. He can have a solid roller camshaft and a single plane intake and head work but the ports have to CC the same as factory. Engine dynoed out at 755HP, he just went 9.52 at 141MPH in a 3400LB 69 Mustang. This is a drag car with open headers that runs a 1.31 60 ft time, not a Cobra. A Cobra is not a set up drag car. The headers, side pipes, rear ends and transmissions kill them.
Blitz's engine made about 715 HP and would run way down in the nines with a very well worked out 2500lb drag car for sure. The more power they make the more the Cobra headers and sidepipes kill them along with everything else. I deal with customers that know what their car will run within a few hundreds so I can not bull **** them with fake dyno numbers.
Once again I knew what was going to happen in these deal if Blitz could get 3/4 of the power to the ground and keep the car straight. Even with my bogus dyno he still got the job done. There are just to many things on a regular car like these Cobra's that kill power before it gets to the rear tires unlike a real drag car, but what do I know.


Thanks, Keith Craft

Good post Keith, always nice to get some insight from a serious engine builder.

IF,

...Blitz could get 3/4 of the power to the ground.

There's the rub with this race,,, could he? Well, clearly he did!

Don't be so lazy...sure you can.

...and when you find it, howza 'bout posting a link here for everbody else?

[Dominik]

Guess what: I did find a spot with free uplink (not so common in Cape Town, nor flatrate) and here it is :-)

http://www.youtube.com/watch?v=hTf0b...mbedded#at=186

That link should be on top of the thread that we don't have to dig for it.

Fantastic!

To add: I never doubted the power of the Cobra, my mate does 10.6 in a street setup car with a FI 428, 500hp. But we all agreed on the traction issue and unused ("Cobra pilot not used to") top speed.

[Jamo]

Good job!

[tin-man]

I'll say this for ya, yu got balls visitin' on this thread for the first time and spoutin' off the way you did.

There are dedicated piston/gear heads, track drivers, engine builders, tranny experts, installers and just plain fun seeking Cobra owners who frequent this site and share their experiences and concerns, build history's, performance expectations and whatever else that is Cobra related they feel the need to opine on and have been doing this for a long, long time.

So before you make another, err, spectacle of yourself, may I suggest you pause for a moment and consider the combined level of experience the 30,000 plus CC membership represents, before you make any more nonsensical assumptions without any foundation or due diligence being performed. Heck you may learn something. Just my two cents........

No harm, no foul pal, its all in good fun, BUT Jamo did let you off light.

He crashed the other dude who had diarrhoea of the mouth, for two years.......

Cheers, tin-man Zhuhai P.R.C.

Look at it this way, Tommy, being a fine upstandin gent n'all is giving Blitz his time in the sun, while wondering where he went wrong. He just spent 300 large on his Ferrari, took what appeared on the surface to be a reasonable bet given his ultra high tech ride with launch control and all the rest of the goodies and still lost.

I'm thinking the next race is gonna be one awesome challenge and one that Tommy will win.

Blitz, be careful, Tom does not get to litigate before the Supreme Court and win by being inconsistent in his judgement as to the eventual outcome of his arguments, [read bets].

Just my two cents, guys.

Ernie.... there's something on your chin.


If it wasn't for the 55 (or so) gallons of tire bite poured down the length of thee track there might have been a different winner. It was so bad I heard than an ATV got stuck at the 60' mark. They had to get it free with a crowbar. I think a set of E70-15 bias plies would have yielded a 10 second run on that infamous day...

[Excaliber]

Dyno numbers for horse power is a continuing debate around. Folks point out a ton of variables and how the numbers can fluctuate so wildly. I think there is some validity to that.

I'll take Keith at his word, that his dyno is "dialed in". But as far as dyno's numbers in general, I remain suspect.

[undy]

I honestly don't think any of the prominent (paranoid) engine builders here try to deceive anyone by "manipulating" dyno numbers. I don't recall any actual accusations here along those lines either... The problem is, the dyno numbers they provide show how much HP & TQ a particular engine can produce on the stand, under very ideal situations. Unfortunately, as Keith said, that is not real world Cobra numbers. Ultra low Cobra RWHP vs FWHP figures tend to be the norm.

Most OEM vehicles seem to have between 11% and 13% power losses between SAE RWHP and SAE "J" FWHP figures, whereby our Cobras show a 20%+ loss.
